Environment: Pollution and Mumbai

This paper presents the dynamics of environmental problems in Iambi city. An evolution concept is applied to study the present environmental status of Iambi. In order to study its dynamics, the entire process of environmental evolution is divided into four types biz. Poverty related environmental issues, industrialization- and arbitration-related environmental issues, rapid economic growth-related environmental issues and wealthy lifestyle-related environmental issues. Dynamics of suitable indicators for all the above issues over the economic development has been studied.

Temporal representation of respective indicator for each type of the environmental problem presented the distribution of these types of environmental problems on a longitudinal scale.

In the analysis it is found that, at present Iambi has prevalence to rapid economic development- related environmental problems. Overpopulated environmental issues show very little significance. Industrialization– and urban-related environmental issues coexist with rapid economic development-related environmental issues. This provides the necessary inputs to city planner so as to avoid various environmental costs that other cities have already experienced.

This influx has created an increased demand for sharing the limited public resources and infrastructure available in the island city.

As the place became scarce the real estate value shot up driving the public to the suburbs.

As a result, expansion of Greater Bombay in 1971 was almost entirely due to its suburbs’ groom. In 1 981 the city’s population of 3. 3 million was far outpaced by the suburb population of 5 million (MAPI 1998). With these trends intuiting Bombay city, in the post-independence period has been facing severe resource constraints.

This growth has further exacerbated the city’s problems by overstraining its services in catering to the hordes of commuters, all heading each morning for south Bombay where the port, business offices and administrative offices are located. High population growth, inward migration and arbitration put stress on resources. Increasing economic activity and per capita income further stresses the resources and “common goods” (BOMBARD 1996). This phenomenon creates a wider scope for increased environmental concerns, which are multifaceted ND also cross-sector. For various social and administrative reasons, Bombay was renamed as Iambi during late 1 sass.

At present Iambi is the largest metropolitan city in India with very distinct characteristics as presented in Table 1 . Environmental management concerns In the history of Bombay, there is not much note Of environmental concerns. Being an island, Bombay has high assimilation potential, which made this city less environmentally concerned (Kombi 1986). However, in light with the above-described features, post-independence era of Iambi witnessed numerous developments, both economically and environmentally. Due to abundant employment opportunities, migration had been so predominant and till 1971 migrants constituted Bombay has been renamed as Iambi during late sass Table 1 Socio-economic indicators of Iambi Indicator Population Literacy rate Employment Per capita income Education Transport Pattern 1 1.

Org the major population growth in Iambi. This has created a wider set of environmental problems biz. Lack of sanitation facilities, lack of drinking water, increased incidence of cholera. Rapid industrialization took place with most of the industrial clusters located in the vicinity of Chamber, which turned it into a “gas chamber with exceedingly high concentrations of air pollution (Pariah et al. 1995).

Increased economic activity resulted in steep rise in transport demands and the vehicular stock. Increased stock of automobiles, most of them being used for decades together, created numerous environmental problems. Ambient air concentrations of Suspended Particulate Matter (CPM), Nitrogen Oxides (Knox) and other hydrocarbons have crossed the allowable limits creating health problems to the Iambi public (World Bank 1997). Increased incidence of tuberculosis was observed, and it is an indicator of the impacts of pollution on Iambi population (Pariah et al. 1995).

Urban transport sector is known for contributing greenhouse gas (GOGH) to the atmosphere. With further economic development and the influence of esters “throw away”‘ cultures, new environmental problems have started cropping up, and increased per capita generation of municipal solid waste (MS) is an example of such development. Lack of appropriate recycling system and infrastructure adds to the problem. Increased per capita energy consumption, particularly in an unsustainable way, creates much more stress on the environment. With the economic development of the city the set of environmental problems keeps changing.

It is clear from the above description that the concerns of environmental management follow a trend: Poverty-related issue?rapid industrialization issues?rapid economic growth- related issues?wealthy lifestyle-related issues. As these issues are cross- sector in nature, conventional environmental management dealing with a particular type of problem fails to address the indirect impacts resulting from environmental issues. Therefore, it is essential to adopt a macro approach with an evolutionary perspective. Environmental evolution: concept and development In cities like Iambi, the arbitration process is coupled with industrialization and followed by rapid economic growth. As explained by ABA 2001), in this process, words like “change” or “growth” can describe the situation far more adequately than “equilibrium” which makes the dynamic viewpoint an inevitable feature in dealing with the urban environment and its management.

The municipalities, which in most countries are the responsible bodies for environmental management, lack long-term understanding and planning of environment. They deal with the environment “as it comes to them”. With such an approach, decisions often tend to be shortsighted and lack broadness in scope. As many of the cities are undergoing rapid change owe, the environmentally benign future of these cities can still be shaped, at least partly. If these cities can learn from the successful experiences as well as failures of other cities, they might avoid paying some of the unnecessary environmental costs their fellow cities have paid (e.

G. Heavy industrial pollution due to the use of primitive technologies). For this purpose, it is essential to have a systematic understanding of how urban environments change and what drives the change. So far, the dynamic feature of the urban environment is treated as a risk rather than an opportunity. It is often shadowed by the overwhelming complexity of the issue.

Viewing this as an opportunity needs an improved conceptual and theoretical understanding about what kind of changes are taking place in urban environment, and how the process is driven. In various studies, ABA and co-workers (ABA and Muar 2000; ABA 2001, 2002) have explained the evolutionary viewpoint of the urban environmental change with empirical evidences from East Asian cities like Tokyo, Seoul, where the most rapid social, economic and environmental changes have taken place over the last several decades. The importance of introducing the temporal dimension and an ecological viewpoint in urban environmental studies was pointed out by Douglas (1988) in his study of Manchester City, England, in which he linked urban growth, physical change and human impact succession. In addition to the temporal dimension, ABA and Muar (2000) further emphasized the importance of viewing urban environmental change as an evolutionary’ process. Often environmental problems are cross-sector and complex.

Categorization of these issues into several types helps to reduce the complexity of the issue. This categorization loud be done based on various parameters like type of impacts, driving forces, etc. Taking into consideration these different driving forces and the spatial scale of the impacts of these problems, ABA and Muar (2000) categorized urban environmental problems into three types: poverty-related issues, rapid-growth and production-related issues and consumption or wealthy lifestyle-related issues. Based on the available literature and criteria used by other researchers (ABA and Muar 2000; Sweatshirts 1997; World Resources Institute 1997), environmental problems in Iambi are categorized into four groups biz. Poverty-related issues, rapid industrialization- and arbitration-related issues, rapid economic growth-related issues and wealthy lifestyle-related issues.

This helps in better understanding of the dynamic process of change in a developing city like Iambi. Table 2 presents typical issues under each category and the major impacts associated and scale of impact. Behavioral patterns of typical issue Poverty-related issues of environmental management are prevalent when the economy is low. Lack of safe drinking water and sanitation resulting in health problems is a classical example of poverty-related environmental issues. Malnutrition results in increasing infant mortality rates (MIR).

As the economy rises, income levels grow and it results in controlling these issues. This falling trend of poverty-related issues continue until the level reaches a significant low. This could be due to the fact that the growing income provides additional resources and capacity to improve public services. Macro-economic approach explains the environmental management and its behavior. When the economy is not strong, production-related activity receives the top priority leaving a wider scope for environment deterioration and resource depletion.

After achieving a certain level of economic improvement the environment gets better due to the increasing affordability to take up pollution control measures and increased awareness and preference for cleaner environment among people. This pattern is often referred to as Environmental Junket Curve (EKE) (Hilton and Hank 1 998; World Bank 1992). Though it is not universally proved for all pollutants, EKE concept explains the behavior of most of the pollutants visit-a-visit economic development. The pattern of this inverted IS curve varies depending on the environmental regulations, tutorial changes in the economy, technological improvement, energy efficiency and trade. Category of consumption-related issues, rapid economic growth-related issues and wealthy lifestyle-related issues, does not improve with economy.

They keep rising with the economy with a possible time lag between them. This trend is observed in cases like per capita MS generation, per capita carbon dioxide emissions, per capita energy consumption and other indicators (World bank 1992; LIND 2002). Reasons for this pattern could be?most of these problems are not of much significance for local governing bodies. As they are global in nature they could e easily externalities. Unlike the local pollution problems these issues fail to catch the public notice, as they are not directly harmful.

Thus, there exists very little incentive for the municipal authorities to Types of urban environmental issues It is a convention to segregate the environmental-related problems into different segments for easy and efficient management of environment. Environmental problems are segmented into water pollution, air pollution, noise pollution, solid waste problem, etc. Due to its easiness in handling and executing counter measure, most of the municipalities adopt this segmented tatter of environmental management. However, many environmental problems are not only cross-sector but also have external impacts which are not captured in the conventional approach of urban environmental management. This classification ceases the opportunity of synergies action between sectors involved in handling the environmental problems.

For instance, focus on response strategies for air pollution control in Iambi could overlook its contribution to the GOGH emission problem. However, by focusing on transportation and related energy issue one can capture both the problems of air pollution and GOGH emissions. Better way to go about this cross-sector environmental problem is to identify the driving force or categorize them based on the type of impacts instead of sectors like air, water and solid waste. This approach provides an opportunity to capture the externalities (like health- and energy-related implications) of the environmental problems as well. This could encompass most of the direct and indirect indicators of environmental concern.

Table 2 Categorization of environmental issues in Iambi Type Type I :Poverty-related issues Typical issues Low access to safe drinking water; intimidation of water bodies Causes Inadequate infrastructure; rapid population growth; income disparity Major impact Spatial extent of impacts Increased incidence of Local infant mortality; sanitation-related health impacts such as diarrhea, cholera Type II :illumination’s- Air pollution, water Rapid industrialization; Industrial pollution Local, regional and arbitration-related contamination; industrial low rates disasters like the one in issues solid waste; poor of emission treatment, lack of Opal, India; disturbance urban sanitation efficient management to the ecosystem; health robbers like tuberculosis due to air pollution Type Ill :Rapid economic CA emissions; Knox Increased mobility; Global warming; acid Local, regional growth-related issues emissions; noise pollution; more emphatic rains; heaps of garbage; municipal solid waste economic activity; less priority blockage of sewers on environment Type IV :Withy Overburdening of energy High consumption; rich lifestyle; Chemical ingredient and Regional, global lifestyle- related and natural resource; low incentives for improvement dioxin-caused issues dioxins abnormalities; overcorrection of resources Andre these issues of global importance while they have much more pressing issues to handle in local domain. The future trends of these issues are uncertain. The curves beyond a certain level of income could stabilize or even decline. But this trend could not be observed even from today’s richest states (ABA and Muar 2000). In spite of various government initiatives to change the consumption patterns, there is no evidence of any downward turn in these curves (COED 1998).

For a poor economy like India, it is possible that the first two types of issues are prominent. However, in the case of Iambi, t is possible to notice both types Ill and IV, as the per capita income levels are much higher compared to the national average. Selection of indicators and analysis of trends For the analysis of the above-listed issues, their behavior with time and space, set of indicators are identified for each stage. These indicators are used to compare the characteristics of the current urban environmental situation. Indicators representing poverty-related environmental issues include population dynamics with detailed indicators such as total population and population growth rates; income levels with detailed indicators such as per pita income; nutrition, health and welfare issues with indicators such as MIR, death from infectious diseases, illiteracy ratio, per capita medical expenses; infrastructure and environmental pollution, with indicators such as access to drinking water and sanitation and incidence of diseases like cholera/ diarrhea.

MIR was chosen as a representative indicator for this category of environmental problems. MIR is the result of malnutrition and is a good measure of the poverty in any city. There is multi-fold decrease in MIR, which is an indication of improved health in Iambi (Raw 1990). It is observed that Poverty-related issues are on a declining trend in Iambi. This is more substantiated by the fact that the Iambi water supply and sanitation status is improving over the last few decades (COM 2002; BOMBARD 1996).

Indicators for the rapid industrialization and arbitration issues include the pattern of industrial growth in Iambi?number of units and employment generation history; GAP contribution of industrial sector; arbitration and employment patterns with indicators such as employment patterns, unemployment levels, arbitration ratio, migration levels; resource use and pollution with indicators such as electricity consumption by industries, CPM levels, SOX and Knox patterns, water contamination. Knox was chosen as a representative indicator for this category of environmental problems. Rapid economic growth phase had started with economic reforms in 1 993 and the pattern of many indicators had changed thereafter. This phenomenon is clearly observed in terms of foreign exchange earned (CAME 2001 http:// www. Indicates.

Com). Other indicators for this stage of environmental problems are increase in vehicular stock, rise in energy demand, air pollution, GOGH emissions and electricity consumption. Electricity consumption was chosen as a representative indicator for this category of environmental problems. Electricity consumption in Iambi has increased substantially. Industry and commercial sectors have equal share in the electricity consumption.

A steep rise from late 1 sass is observed (http:// www. Indicates. Com). This rise in consumption could be attributed to economic growth and increased per capita incomes as well as increased economic activity. Indicators for rich and wealthy lifestyle are not significant in Indian context.

However, given the better economic status that Iambi enjoys among the Indian Intensity of the Problem (on normalized scale of 0-1) Fig. Illustration of different types of environmental problems spanned over economic growth in Iambi MIR MS KNOX Electricity 1920 1930 1940 1950 1960 1970 1980 1990 2000 201 0 2020 Year cities, there are traces of these indicators showing significance in the case of Iambi. MS generation, electricity consumption, changes in petrol and gas reserves are the indicators of this category of issues. Percentage of growth in solid waste has increased considerably which is an indicator of increased institution patterns and rich lifestyle that Iambi public enjoys. MS management is one of those very serious problems that Iambi is facing at the moment (Sarnia 2004).

MS was chosen as a representative indicator for this category of environmental problems. Therefore, the stage IV type issues are also identified and analyzed in Iambi. Though it is not possible to predict the future trends/behavior, it helps in assessing the “environmental status” of the city. Are closely clustered. This indicates that the three zones are coexisting in this city of high economic growth and promise.

However, it is possible to identify which one is predominant and which one is in phasing out stage. Future trends of electricity consumption (stage Ill) and waste generation (stage IV) cannot be predicted. The projected values of MS clearly indicate the rising trend with time. A similar trend is observed with electricity also. As it can be seen from Fig.

, Iambi at present stands at stage Ill facing more of rapid economic growth stage-related environmental issues. Poverty-related issues are not of major concern any more whereas there is a spillover from stage II, industrialization- and arbitration-related issues. Stage Ill issues and stage IV issues coexist in Iambi with both of them following rising trends.

In spite of the fact that Iambi presents one of the efficient public services in the country, poverty level is still high and overcrowding is causing lapses in the system. However, the significance of poverty-related environmental issue is not very high. The representative indicator under this category revealed a steep declining trend.
